Abstract: It was a great challenge for Sulige gas field to reach the target of economical scale development using traditional management mode under the situation of low single well production and large well number. A gas well head remote control electromagnetic valve was designed on the basis of technical research and test. It was characterized by small volume and new structure. With the power supplied by solar energy and without external gas sources, the valve was opened and closed by means of switching pressure relief hole and it was self-holding. Over-under pressure protection and remote control function were realized through the available wireless remote transmission and control system. Applying the valve in Sulige gas field, artificial opening and closing gas well were substituted, and difficult problems of gas well production and management were solved. It has become the key technical equipment for digital construction in Sulige gas field.

Key words: gas field, electromagnetic valve, over-under pressure protection, remote control, solar energy
